Hongos que causan damping-off en el tomate y control con Trichoderma harzianum cepa A34 para el manejo integrado de plagas del cultivo en Cuba.

Urban Farm DB summary

This study identified major fungal species causing damping-off in tomato seedlings in Cuba, with Rhizoctonia solani present in 50% of samples, Phytophthora parasitica in 41%, and Pythium aphanidermatum in 8.3%. Seed treatment with the antagonist Trichoderma harzianum (strain A34) increased germination to 100% in Floradel, Lignon, Placero, Criollo, and Campbell-28 varieties, compared to 70-80% in untreated ones. This treatment also increased seedling weight and fruit size, and for the Placero variety, it resulted in over 50% higher harvest, yielding a profit of $560.12.
